2' '0 all whom it may concern:

Be it known that I, Gnonen E. Mrrrmcnn, a citizen of the United States, residing at Cleveland Heights, in the county of Cuyahoga 5 and State of Ohio, have invented certain new and useful Improvements in Crimping Tools, of which the following is a specification, reference being had therein to the accompanying drawing. v

My invention relates to an improvement in a crimping tool whichis particularly desi ned for crimping or fastening in the heads or covers of metallic kegs, barrels, or the like.

My present invention relates to a crimping tool particularly adapted to crimp or fasten a one-piece cover or head in the central ring opening of a keg or barrel. I have found that for certain purposes it is of advantage to have a one-piece cover.

In using a one-piece cover for closing the opening in a barrel end ring it is necessary to provide a means for fastening the cover in the ring. My improved crimping tool, shown in the accompanying drawings and hereafter more particularly described, accomplishes this result.

It will be readily understood that the principle of my invention can be utilized in crimping heads or covers in barrels or kegs of many kinds without departing from the spirit of the invention. The crimping heads could be very easily and readily constructed to provide a crlmp of a different 36 shape should this be desired to meet with any particular use to which the tool has to be applied.

The object of my invention is to provide a crimping tool so constructed as to readily 40 and easily crimp or fasten heads or covers outwardly as at12.

in metallic barrels, kegs, or the like.

Another object of my invention is to provide a tool for crimping heads or covers in J metallic barrels kegs or the like, which will fasten the heads in place securely yet at the same time so fasten them that the heads can be removed when desired.

Another and further object of my invention is to provide a tool for the purpose desired which is simple and cheap of manufacture and highly efficient in operation.

Other and further objects, novel features and improved results of my nvention will appear in the following description and ac- I companying drawings.

' In the drawings:

l ligure 1.is a top view of my'improved too ,Fig. 2 is a view in side elevation of my improved tool.

Fig. 3 is a vertical sectional view of my improved tool,'one of the barrel heads being shown in place upon the crimping element in full line and the extended position of the crimping elements and the criznped barrel head being shown in dotted lines. v

Fig. 4 is a fragmentary vertical sectional view of a portion of the tool, the barrel head and barrel end ring, showing the crimping elements of the tool in extended position and the'barrel head locked within the barrel head ring.

Referring to the drawings which show a specific form of my improved tool which is adapted to the particular work of fastening a head or cover in a barrel of the charing, and said wall terminates in a vertical portion 9 adjacent to the top edge of the collar 7.

Mounted within the opening 6 of the base 5 and adapted to reciprocate therein is a cylindrical stud 10 of a diameter to fit within the vertical wall portions 9 of the opening and be guided thereby. The lower end 11 of the stud 10 is tapered or flared Carried beneath the Washer 5 are the four crimping elements or members 13, the inner edges of which have a tapered wall 14, which are in engagement with the tapered wall 12 of the enlarged head 11 of the stud 10. Due to this engagement the crimping members are supported at their inner edges by the lower end of the stud while the outer ends'of the crimping members are supported by four bolts 15 which extend downwardly through the elongated slots 16 in the base or washer 5. The lower ends of the bolts are in screw-threaded engagement with the crimping members 13 as at 17, while the upper ends of the bolts are provided with the usual...heads 18-beneath whichis mounted awasher 19.

"Vithin the upper end 20 of the'stud 10 is mounted a bolt 21 provided with the usual head 22. This bolt clamps or fastens upon the top 20 of the stud, the horizontal leg 23 of a U-shaped frame, the'vertical legs 24 of which extend downwardly in separat-' ed parallel relation with the stud 10. Mounted onopposite sides of the stud 10 upon a shaft 25 which penetrates both of the vertical arms 24 of the U-shaped frame and the stud 10 are the lower camends 26 of the two\ elongated handles 27. a As clearly appears in the drawings the lower cam ends 26 of the handles 27 are in engagement with an upper raised portion 28 carried by the top-of. the collar 7 of the base 5.

Referring now to the crimping membels 13, particularly toFigs. 3 and 4 of the drawings, it will be seen'that the inner edges or'ends of these members are provided with an upstanding flange or collar 29 which extends upwardly into the space or -cutout portion 30 in the lower face of the base 5. To hold the crimping members in contracted osition' I have provided a' series of coiled springs 31 which are carried in suitable openings in the base 5' and extend outwardly into the space or cut-out portion 30 where they are in engagement with the collars or flanges 29 at the inner ends of the crimping members. The action of these springs is to push in upon the collars 29 and it will be clearly seen that this pressure will hold the crimping members in contracted position.

The outer edges of the crimping members are provided with an approximately U- shaped bulge or projection 32 throughout their peripheries. The outer edge of the base5 is provided with an L-shaped flange or seat 33 which is adapted to rest uponandreceivethe top edge 34 of the barrel cover. The barrel cover appears in Figs. 3 and 4 of the drawings'and is approximatel U- haped having a flat bottom 35 surroun ed by a vertical wall 36.Which terminates in the "horizontal top 34 before mentioned.

Referring now to Fig. 4 it will be seen that the horizontal top edge 34 of the barrel cover is supported upon the inner horizontal portion 37 of the barrel ring 38. Although it is not absolutel essential, the inner horizontahportion 3 of the barrel ring 38 terminates in a downwardly extendin edge 39. From the foregoing description it will be seen that the enlarged lower end 11 of the stud 10 is the only connection link be- 13 are insertedupon thebottom 35 placed upon the supporting portion 37 of the barrel ring and the crimping members of the cover within its vertical walls 36.

During this portion of the operation the handles 27 are in a raised position and the springs 31 are functioning to hold the crimping members in contracted position.

To effect a locking of the barrel cover in lace the handles 27 are grasped and pull ed downwardly. As the. handles are lowered, the cam end s 26 engage the upper portion 28 of the base collar 7 which moves the stud 10 upwardly. As the stud 10 rises the tapered wall 12 of its enlarged end 11' engages the inner tapered ends of the crimping members 13 and push them outwardly against the tension of the springs 31. The crimping members are guided in their outward movement by the supporting bolts 15 iwhiclg slide in the elongatedslots 16 in the When the handles 27 have reaQzhed the'bottom of their downward movement the crimp ing members 13 are in the position shown in the dotted lines in Fig. 3 and the positions also shown in Fig. 4 of the drawings. The circumferential extending portion 32 of the crimping members 13 has engaged the vertical wall 36 of the cover and crimped or bent this wall the supporting wall or portion 37 of the barrel ring 38 as clearly appears at 40 in Fig. 4 of the drawings. This crimp 1s sufiiciently great to hold the cover in the barrel ring yet it will be found that when have provided a tool by which the barrel heads can be readily crimped or locked in the barrel ring. It is-a rapid procedure to place the tool within the barrel press the handles of the tool once and outwardly beneath cover, to

bring them backto a raised position again.

This one movement effects a complete looking of the head and the cover in the barrel ring. When the handles are brought back to a raised position the springs 31 automatically return the crimping members to a contracted position so that the tool canvbe removed from the cover and be ready for immediate insertion within another coyer for a repetition of the operation.

It will also be readily apparent that my improved tool is simple of construction, cheap of manufacture and highly eflicient in-operation.

It should also be understood that the outer edge of the crimping members can be constructed to provide acrim of any shape desired and that the tool 1s, there fore, not limited to use in the particular manner heretofore described.

Having thus described my invention what I claim and desire to secure by Letters Patent is': l a
